Hypericum plant named ‘Bosaja’

ABSTRACT

A new and distinct cultivar of Hypericum plant named ‘Bosaja’, characterized by its upright and outwardly spreading plant habit; dark green-colored leaves; shiny green-colored fruits; and good postproduction longevity.

Botanical classification/cultivar designation: Hypericum androsaemum cultivar Bosaja.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Hypericum plant, botanically known as Hypericum androsaemum, commercially used as cut stems with fruits, and hereinafter referred to by the name ‘Bosaja’.

The new Hypericum is a product of a planned breeding program conducted by the Inventor in Rijnsburg, The Netherlands. The objective of the breeding program was to develop cut Hypericum varieties with attractive fruit coloration.

The new cultivar originated from a cross-pollination made by the Inventor in July, 1991 of a proprietary selection of Hypericum androsaemum identified as code number 3, not patented, as the female, or seed, parent with a proprietary selection of Hypericum androsaemum identified as code No. 189, not patented, as the male, or pollen, parent. The cultivar Bosaja was discovered and selected by the Inventor in July, 1993 as a flowering plant within the progeny of the stated cross-pollination in a controlled environment in Rijnsburg, The Netherlands.

Asexual reproduction of the new Hypericum by terminal cuttings taken at Rijnsburg, The Netherlands since March, 1996, has shown that the unique features of this new Hypericum are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bosaja’. These characteristics in combination distinguish ‘Bosaja’ as a new and distinct cultivar:

1. Upright and outwardly spreading plant habit.

2. Dark green-colored leaves.

3. Shiny green-colored fruits.

4. Good postproduction longevity.

Plants of the new Hypericum differ from plants of the parent selections primarily in fruit coloration.

Plants of the new Hypericum can be compared to plants of the Hypericum cultivar Bosapin, disclosed in U.S. Plant Pat. No. 10,993. In side-by-side comparisons conducted in Rijnsburg, The Netherlands, plants of the new Hypericum differed from plants of the cultivar Bosapin in the following characteristics:

1. Plant of the new Hypericum were shorter than plants of the cultivar Bosapin.

2. Plants of the new Hypericum had smaller leaves than plants of the cultivar Bosapin.

3. Plants of the new Hypericum had smaller fruits than plants of the cultivar Bosapin.

4. Plants of the new Hypericum had green-colored fruits whereas plants of the cultivar Bosapin had light red-colored fruits.

Plants of the new Hypericum can also be compared to plants of the Hypericum cultivar Bosakin, disclosed in U.S. Plant Pat. No. 10,994. In side-by-side comparisons conducted in Rijnsburg, The Netherlands, plants of the new Hypericum differed from plants of the cultivar Bosakin in the following characteristics:

1. Plants of the new Hypericum were shorter than plants of the cultivar Bosakin.

2. Plants of the new Hypericum had smaller leaves than plants of the cultivar Bosakin.

3. Plants of the new Hypericum had smaller fruits than plants of the cultivar Bosakin.

4. Plants of the new Hypericum had green-colored fruits whereas plants of the cultivar Bosakin had dark red-colored fruits.

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Hypericum.

The photograph on the first sheet comprises a side perspective view of typical plants of ‘Bosaja’ in fruit.

The photograph on the second sheet is a close-up view of a typical plant of ‘Bosaja’.

The photographs on the third and fourth sheets are close-up views of typical leaves, flowers and fruits of ‘Bosaja’.

DETAILED BOTANICAL DESCRIPTION

The new Hypericum has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown in Rijnsburg, The Netherlands, in an outdoor nursery and under commercial production practices. Plants were about two years old. The photographs and description were taken in September when outdoor day temperatures ranged from 14 to 27° C. and day temperatures ranged from 5 to 14° C. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
